LOZENGE- MACHINE.

SPECIFICATION forming part of Letters Patent No. 376,068. dated January 10, 1888.

Application filed Ncveulhr-r 24, 1886. Serial No. 219.750 (No model.)

To all whom it may concern.-

Be it known that I, OLIVER It. CHASE, of Boston, in the county of Suffolk and State of Massachusetts, have invented. certain new and useful Improvements in Machines for Manufacturing Lozenges, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to machines for manu-- facturing confectionery, and especially confectionery lozenges, and is an improvement upon the machines described in Letters Patent Nos. 279,132 and 279,913, granted to me June 12,

1883, and June 26, 1883, respectively; and it A bon of, say, six or eight inches in width and less.

about one-half an inch in thickness, more or The sheet or ribbon so formed was then taken by hand from said machine and transferred to thefeedi'ng-apron of the machine described in Letters Patent No. 279,913, where it was further reduced in thickness,planished, and then cut into lozenges... This mode of operation involved the running of two independent machines and an extra handling of the material, which my presentinvention obviates.

In the drawings, Figure 1 is a side-elevation of a machine embodying my invention. Fig. 2 is a longitudinal vertical section of the same. Fig. Sis a transverse vertical section on line 1 1 on Figs. 1 and 2, looking toward the delivery end of said machine, said figure being drawn to an enlarged scale. Fig. 4 is a vertical longitudinal section of a portion of the delivery end of the machine, also drawn to an enlarged scale. Fig. 5 is a side elevation of the upper portion of Fig. 4, looking in the opposite direction to that in which Fig. 4 is viewed, and drawn to the same scale'as Figs. 3 and 4. Figs. 6 and 7 are details illustrating the manner of vibrating the printing-forn1 and holding it in position while giving animsection of the stripper-bar.

pression or taking ink. Figs. 8 and 9 are respectively aplan and an elevation of the oscillating type-carrying bar. Figs. 10 and 11 are respectively an elevation and a transverse Figs. 12,13, and 14 are respectively an end elevation,'a transverse section, and a front elevation of the rectangular discharge-nozzle for forming the sheet of sugar-paste; and Fig. 15 is an inverted plan of a portion of the cutters. the embossing and printing bars, and the bail-like stand for carrying said bars. Fig. 16 is apartial longitudinal section illustrating a modification, to be hereinafter referred to.

In the drawings, A A are the side frames of the machine, connected together by the tiegirts A A and the plates A" and P,as shown in Fig. 2.

Upon theplate A is mounted the vertical cylinder B, provided with the revolving screwpiston B and one or more horizontal screwfeeders, B all constructed, arranged, and operating substantially as described in the said Letters Patent No. 279,132, and with the inclined feedtable'B from which the material is fed to the cylinder B, from which it. is discharged in 'the' form of a sheet or ribbon, a, through the rectangular opening 6 in the nozzle O, as shown in Fig. 2. The nozzle 0 has pivoted therein the plate I), the free or outer edge of which may be adjusted by the setscrews 1), for the purpose of varying the thickness of the sheet of material that can be delivered therefrom, as shown in Figs. 2, 13, and 14. The sheet of material a, when delivered from said nozzle, falls upon the inner end of the apron b", mounted upon the rolls b and I)", and is carried by said apron beneath the endless band or apron c, mounted upon the rolls 0 and c and upon the moving apron or endless band 0 mounted upon the rolls a and 0 as shown in Fig. 2. The sheet of material, as it passes from the apron 0 where said apron passes around the roll 0 is turned downward between the pressure-rolls d and d, .where it is reduced in thickness and compacted, and then between the planishing-rolls d and d and deposited upon the moving apron e, mounted upon the rolls a, e, and 6 as shown.

The rolls (1 and d are partially surrounded by the endless bands. or aprons d and d :respectively, which extend to and partially surround the rolls (1 and d respectively, as shown. The aprons b, c, d, and d each have placed thereon a quantity of flour or powdered starch within a shallow hopper or receptacle, f, of which said apron forms a moving bottom, as described in said Letters Patent No. 279,913, whereby the sheet or ribbon of paste has deposited upon each side thereof a thin coating of said flour or starch to prevent it from adhering to any of the aprons or the planishingrolls. The aprons b, c, d", and (1 may be made taut by adjusting the rolls b", d, and d in any well-known manner.

The screw pistons or feeders B and B are driven from the shaft D in the same manner as described in the before mentioned Letters Patent No. 279,132, said shaft D being driven by a belt (not shown)-leading from the drivingpulley D to any suitable counter-shaft. (Not shown.)

The shaft D has mounted thereon the pul ley D from which the belt D leads to the pulley D, mounted upon the shaft D which has its bearings in the frames A A, and has secured thereon the pinion g, which engages with and imparts motion to the gear-wheel D on the shaft 9, also mounted in bearings in the frames A A,and having mounted thereon the pinion 9 which engages with and imparts motion to the gear-wheel E, mounted upon one end of the shaft of the roll If, the opposite end of which shaft has secured thereon the gear-wheel h, which engages with and imparts motion to the gear-wheel h, mounted upon the shaft of the roll 0, as shown. The shaft of the roll b has mounted thereon a pulley, from which the belt It leads to a similar pulley on the roll 0 for the purpose of revolving said roll 0 in unison with the roll I) and imparting motion to the apron 0 for conveying the sheet of paste a to a position to be delivered to the pressure-rolls d and d, as shown. The upper portions of the endless belts c" and e are supported between their carrying-rolls by the bed-plates or tables 0 and c respectively, as shown in Figs. 2 and 3.

Motion is imparted to the rolls (1, d, (1 and d and the aprons d and d from the roll 0 by means of the gear-wheels i i, i, i i", i, i, and t".

The endless apron e has an intermittent motion imparted thereto by means of the cranl pin i, set in the disk 2', mounted upon one end of the shaft F, the connecting-rod F, the lever i, the pawl i and the ratchet-wheel i", mounted on the shaft of the roll 6 in substantially the same manner as described in said Letters Patent No. 279,913.

The shaft F has mounted thereon the gearwheel F with which the pinion F, mounted upon the shaft G, engages, to impart to said shaft F a rotary motion, said shaft G being revolved by means of the pulley G, mounted thereon, and a beltleading therefrom to a suitable counter-shaft, which may be the same from which the shaft is driven or an independent one, as may be preferred, care being taken to so proportion the several pulleys that said shafts G and D shall be driven at the proper relative speed.

The shaft F has mounted thereon two eccentrics, H and H, which work in slots in the lower ends of the vertical bars H" and H", respectively, in such a manner as to impart to said bars a vertical reciprocating motion, said bars being fitted to slide in dovetailed bearings in the inner faces of the stands I and l, bolted to the upper edges of the frames A A. as shown. To these bars II and H is bolted the horizontal bar H, having set therein a series of tubular cutters, It In, which project downward therefrom and surround the fixed pistons l, suspended from the under side of the fixed bar J, said cutters, when moved downward to cut lozenges from the sheet of material (6, passing through holes in the fixed bar J, supported upon the raised ribs of the bed-plate e, as shown in Fig. 3. The shaft F also has mounted thereon the eccentric m, which works in the strap end of the eccentric-rod m, which in turn is connected to the lever m", firmly secured upon the rocker-shaft m, mounted in bearings in the frames A and carrying the two arms at m the free ends of which are connected to the rods n at, having bearings in the stands I and l and carrying at their opposite ends the reciprocating lozengecarrying plate a, all constructed and operating substantially as described in said Letters Patent No. 279,943, except that the plate n, instead of having a jointed flap, as described in said patent, has a fixed raised rib, n", upon its inner edge, and except, also, that instead of the lozenge being brushed from the inner edge of said plate as said plate is moving outward, as described in said patent, the lozenge is removed from the outer edge of said plate as it ismoving inward afterhavingbcen moved outward, as will be further described. The plate on also has at each end thereof the raised cam-shaped rib n 1r, arranged to act upon the pendent arms of the elbow-levers a", pivoted upon the arms or rods a to move said levers about their pivots and raise or lower the stripper-bar J, fitted to move vertically in slots a, formed in the outer ends of the arms 12 as shown in Figs. 1 and 4.

The stripper J is composed of the central plate, 0, arranged to fit the slots at and to rest upon the free ends of the horizontal arms of the elbow-levers n at 0, thetwo plates 0 and 0*,and the sheet or plate of vulcanized rubber 0*, all secured together by screws or rivets, as shown in Figs. and 11.

\Vhen the platen is moved'outward, after having received from the cutters a series of lozenges, the outer throws of the cams a coming in contact with the pendent arms of the levers or causes the stripper-bar to be raised and held in such raised position until the lozenges on said plate have passed outward beyond the rubber flap of the stripper-bar, when the inner throws of the cams n will have passed from beneath the levers a, when the stripper-bar will descend to a position with the lower edge of the rubber flap 0 on alevel with the upper surface of the plate n behind 1 be at a considerable distance from the roll 10" and mounted upon an independent stand,from which apron the lozenges are delivered to a board or receptacle provided for the purpose.

Motion is imparted to the rollp by the gearwheels K and L, mounted, respectively, on the shaft F and the shaft of the rollp, as shown in Figs. 1, 2, 3, and 4. I A standard, M, is firmly secured to the upper end of each of'the stands I and I in such a manner that it may bev readily removed by simply slackening the nuts 19 p and raising said standard to lift the holding-bolt out of the open slot p in the stand I and I. In bearings formed in the upper ends ofthe standards M is mounted the roll q,and in bearings formed in thelower ends of said standards are mounted the two smaller rolls, g g, and the impression bar or platen q", around which is strained the endless band q of cloth, to serve as a coloupad, upon which coloring-matter for printing mottoes in color upon the lozenges is distributed from the color-roll r by the cylindrical brush r, assisted by the distributing-roll 1, as shown in Fig. 4. Rotary motion is imparted to the brush r by means of the belt r leading from the pulley N on the shaft G to the pulley N" on the shaft of said brush, as shown in Fig. 4, and the roll r is revolved by means of the pinion 17 and gear-wheel r mounted, respectively, on the shaft of said brush r and the shaft of said roll 1', as shown in Fig. 1.

A bail-like stand, 0, is securely bolted to each of the vertical] y-reciprocating bars H and H so as to move up and down therewith, and upon its lower bar is adjustablysecured the bar 1, from which is suspended so as to be adj ustable vertically, by means of the threaded bolts 1 and the nuts 7' and r, the bars, having formed in or secured to its under side a series of dies adapted to emboss upon the sheet of sugar-paste a row of ornamental figures or designs corresponding, in number and distance apart from center to center with the number and distance apart of the cutters k k, said bar 0' being secured to the stand 0 at a distance from the center of the line ofcutters k k corresponding to a multiple of the distance which.

' terchangeabl y inserted in either of the holes 8,

formed in said bar for the purpose, as shown in Fig. 15. j

The shaft 0 projects beyond'its bearings at each end, and has formed upon one of said projecting portions a tooth, 8 which engages with the rock-like teeth 8, formed on the edge of the stand I, as said shaft is moved up and down with the stands 0, thereby imparting to said shaft a semi-rotation about its axis. (See Fig. 6.) The opposite projecting end of said shaft is made square, and acts in conjunction with the edge oft-he stand I to maintain said shaft in afixedposition as to rotation after it has been moved about its axis a half-revolution both in its upward and downward move ment, the edge of said stand 1 having a recess, 8", formedtherein at the proper point and of the proper length to permit the rotation of said shaft when the tooth s engages with the teeth 8*, all as shown inFig. 7.

The shaft 0 has suspended therefrom, by means of the threaded bolts 8 s and nuts 8 s, the bar 8 which may be adjusted toward or from said shaft by said bolts and nuts and the set-screw s", as shown in Figs. 8 and 9. The bar 8 has secured thereto the plate t, of type -metal,having cast thereon a series of mottoes, the type composing which project from the surface of said plate, and in the operation of the machine are alternately brought into contact with the endless-belt pad (1 to take color 7.

therefrom and into contact with the upper sur-- IOO face of the sheet of sugar-paste a to print said mottoes thereon, these operations being accomplished by the upward and downward movement of the stands 0 and the bars H and H, caused by the rotation ofthe eccentrics H and- H.

In order to present a fresh portion of the Y of the ratchet-wheel 16 secured upon the shaft of said roll g by the preponderance of weight in the long or outer arm of said pawl, the whole being so arranged that every downward movement of the stand 0 causes a partial straightening of the toggle, and as a consequence thereof a partial rotation of the roll q and a movement of the color-band aroundthe same. When the stand 0 is again moved up ward, the pawl t is carried backward over the teeth of the ratchet-wheel t preparatory to its engaging with another tooth of said wheel,

when the stand 0 is again moveddownward.

P is the-inclined plate down which the waste from which the lozenges have been cut slides and falls into any suitable receptacle provided for the purpose.

The rubber [lap o of the stripper-bar J has its lower edge divided into a series of sections by vertical slits, as shown in Fig. 10, so as to present less resistance in case a lozenge should stick to the plate a when said plate is moving backward beneath the stripper-bar.

The operation of my invention, I think, will be readily understood from the foregoing without further ex' 'ilanation.

In some cases I propose to dispense with the aprons c, d, and d and the rolls 0", d, d, d, and (t and place the rolls d" and d directly below the rolls 1/ and 0, respectively, said rolls 1) and 0 being adjusted to the proper distance apart, as shown in Fig. 16, whereby the machine may be considerably reduced in length.

What I claim as new, and desire to secure by Letters Patent 01' the United States, is-

1,. The combination of the intermittentlymoving belt or apron c, the shaft F, the eccentrics H and II, the bars H and 11, the series of cutters k, carried by said bars, the oscillating shaft 0, also carried by said bars and having-one end thereofsquarcd,aud having formed upon the other end the tooth s, the type plate or form 2, carried thereby, the stand 1, provided with the teeth 8, the stand 1, provided with the curved or cutaway place 8", the rolls q and f q, the endless color-carrying belt q,

belt 0, all arranged and adapted to operate l substantially as described.

4. The combination of the apron e, the cutters 7:, the plate a, and the stripper-bar J, provided with the pendent rubber ilap 0", divided into sections by vertical slits, substantially as described.

In tcstinionywhereot' I have signed my name to this specification, in the presenceof two subscribing witnesses, on this 2d day of November, A. D. 1886.
